24 Claims.

This invention relates to a mop wringing device, and while the inventionmay have various applications, it particularly is designed as a mopwringing device adapted to be carried by a pail in which the wash wateror rinsing water for the mop is carried. While various mop wringingdevices have been proposed, it has heretofore usually been necessary forthe operator to operate either a manual or pedal lever for squeezing themop.

"'- In the particular type of mop wringer or squeezer illustrated, ithas usually been the practice to provide a lever located quite close tothe pail for moving the mop squeezing elements together. Thisnecessitated the operator stooping over and usually getting his facemore or less directly over the hot water in the pail. Such an operationis tiring and unpleasant.

It is an object of this invention, therefore, to provide a mop wringingor squeezing device cornprising members movable towards each other, to-Igether with means adapted to be engaged by the handle of the mop so thatit is merely necessary to swing the handle oi the mop with the mopbetween said members, to squeeze the mop. The

handle can be easily swung without the operatorv having to bend oververy far.

It is a further object -of the invention to pro vide a mop wringing orsqueezing device adapted to be used with a pail and comprisirrf airaine, a pair oi swinging plates movable toward and from each othercarried on said traine, one ol' said plates having an upwardly extendingportion with means adapted to be engaged by the mop handle whereby ahandle equipped mop can be placed between said plates, the handleengaged with said means, and said handle and plates moved to squeeze themop.

It is still another object of the invention to provide a mop wringing ormop squeezing device comprising a frame adapted to be supported by apail, a pair oi revolubly movable members or plates mounted in saidrame,.a roller engaging one of said plates for moving the saine, saidroller preferably being adjustable to vary the movement of said plate,together with means for moving the other plate to cause approachingmovement of said plates.

Itis still another object of the invention to provide a mop wringingdevice comprising a swinging plate and a device of novel form carried bysaid plate adapted to be engaged by the mop handle to be moved therebyto swing said plate.

These and other objects and advantages of the invention will be fullyset forth in the following the accompanying drawings, in which likereference chai"-y acters refer to similar parts throughout the severalviews, and in whichz'- Fig. l is a view in side elevation of a mopwringing device embodying the invention, a pail being shown partly insection;

Referring to the drawings, a pail 10A is shown of substantiallycylindrical form having a slight are towards its upper end and equippedwith a bead at its upper end. A mop' wringing device is shown comprisinga frame designated generally as ll, said frame comprising parallel sidemembers lla connected at their bottoms by a portion 1lb thus forming asubstantially U-shaped frame. Members 11a have plates 12 riveted theretoand extending parallel thereto, said plates having downwardly extendingportions 12a forming in eiiect hooks adapted to extend over the top edgeof the pail 10 at spaced points to support the frame 1l. The sidemembers 11d are apertured at their upper ends to receive a rod 13extending therebetween, the' same having a cotter pin 14 extendingtherethrough at one end at the outer side or" one of said side platesand having its end bent downwardly and then inwardly substantially atright angles at its other end forming the portion 13a. Portion 13aisadapted to engage with the edge of a plate 15 secured to one of theplates l2. A bolt 16 eX- tends through plates l2 and 15 and through aslot 15a in the plate l5 and is threaded at its outer end to be engagedby a thumb nut 1'7. Plate `15 can thus be moved upwardly and downwardlyand held in different positions by tightening the thumb nut 17. Themember 13a will thus be held in diierent positions according to theposition of plate l5. A member designated generally 2 as 1B is traversedby the pivot rod 13 and swingable about the axis of said rod. Saidmember 18 comprises a rear plate 18a and side plates 18h extendingforwardly therefrom substantially at right angles. The side plates 18hare substantially of sector-shape, having curved upper ends which arebent slightly outwardly. A pair of angle bars 19 are secured to the rearof plate 18a, which plate extends upwardly in substantially triangularform, said angle bars being secured in any suitable manner as by therivets shown. Bars 19 extend above plate 13a in slightly spaced relationand a flat bar 20 is secured between bars 19 and extends thereabove, thesame having secured thereto a plate 2l which has a narrow strip at oneend, one portion of which iits alongside of bar 20 and is apertured tohave pass therethrough a screw 22 secured in the bar 20 and have a headcountersunk in said bar. Screw 22 is equipped with a nut 23 and acompression coil spring 24; surrounds said screw and is disposed betweensaid nut and plate 21. Plate 21 has an end portion 21a extendingoutwardly and curved A laterally from bar 20 and said plate has a muchwider portion 2lb curved into substantially semicylindrical shape toform a hook. Portion 2lb has its concave portion covered with a softleather member 25, the edges of which are folded over the edges ofportion 2lb and held in place at the outer side of said portion by thelacing 26. The

free edge of the semi-cylindrical portion of member 21 extends in aninclined direction so that the opening at the side thereof is wider atthe lower end than at the upper end. The plates 18h have a reinforcingstrip 18o extending across the front thereof at their upper innerportions, the ends of said strip extending across the plates 18h attheir outer sides and being riveted thereto. A plate 27 is provided,adapted to extend between the plates 18h, said plate being slightlycurved in a compound curve as shown in Figs. 1 and 3. Said plate is bentat an angle adjacent one end and has an eyelet formed at its lower endtraversed by a pivot pin 23 which extends through and between plates18h, being held therein by being headed at one end and having a cotterpin 28a extending therethrough at its other end. A torsion spring 29 isdisposed at each end of the pivot pin 28 surrounding the same and havingone end bearing against plate 27 and its other end bearing against plate18a in the corner between the latter and side plates 18h. These springstend to keep plate 27 moved away from plate 13a, and moved against strip18o. Bars 30 l' are pivoted by the headed rivets 31 at their lower endsto the side members 11a, said bars extending upwardly and havingextending therebetween and secured therein the headed pin 31 havingcollars 32 thereon between the ends thereof and between the same andbars 30 are disposed rollers 33. These rollers engage the outer side ofplate 27 and act in the operation of the device to move said platetoward plate 18a. Bars 30 are bent slightly intermediate their ends andjust below said bends they are disposed alongside of the plates 12bsecured to and extending inwardly from said members 11a, said platesbeing shown as forming part of the plates 12. The plates or portions 12bhave a plurality of holes 12o therethrough and headed and nutted bolts34 pass through one of these holes and the bars 30 so that said bars andhence the rollers 33 can be held in different positions. A drain pan 35is secured to side members 11a, the same having a narrow ilangeextending about its sides and rear end and having a bottom incliningdownwardly into the pail 10. Plate 27 is provided with a plurality ofholes 27a and said plates 18D are provided with a plurality of holes18d, these holes being provided for the Vpassage of the water when themop is squeezed.

In operation the device will normally occupy the position shown in Figs.1 and 2. The wash water will be placed in the pail 10 and when it isdesired to rinse and squeeze the mop, the wet mop will be placed in thepocket formed by plates 18a, 18h and 27, which pocket, as clearly shownin the drawings is the shape of a sector of a cylinder. The mop isplaced in said pocket and the operator then moves the handle 36, shownin dotted lines in Figs. 1, 2 and 3 into the portion 2lb of plate 2l,the same moving between the end of said portion and the portion 21a. Thehandle is then engaged in the semi-cylindrical portion 2lb and swungforwardly transversely of the pail l0. The opening in member 21 beingwider at the bottom facilitates the entry and exit of the mop stick.When the handle exerts pressure on portion 21h it pivots on the bolt 22and swings into the position shown in dotted lines in Fig. e, so that itis directly in front of bar 20. The operator now merely swings the mophandle forwardly and plate 18a is moved to the left as seen in Figs. land 3, plates 18h moving at the side of plate 27. Plate 27 is engaged bythe rollers 33 and as plate 18a swings toward the left, the rollers moveupwardly on plate 27 and it is moved toward plate 18a. The mop is thussqueezed between plate 27 and plate 18a. The water squeezed from thernop passes through the holes 18d and 27a and also runs down betweenplates 13ar and 27 into the drain pan 35 from which it runs down intothe pail l0. It will thus be seen that the operator can squeeze the mopwithout bending down low over the bucket of hot water. All thatnecessary is -merely to hold the mop handle at a point high above thebucket and swing the handle forwardly over the bucket. When the handleis swung back, the springs 29 again move plate 27 to its normal positionand the mop can be lifted from between plates 18a and 27. The rollers 33can be located in different positions by placing the bolts 34 indifferent holes 12e. This causes a diierence in the distance the plates18a and 27 are spaced and also varies the leverage exerted on plate 27in squeezing the mop. By moving the plate 15, the portion 13a of thepivot 13 is stopped in a different position and this results in themember 19 being held in a more nearly vertical position. rihisadjustment is provided so that member 19 will not extend at too great anangle to the vertical so as to accommodate buckets with dii'lerentdegrees of flare and to suit various operators.

In Figs. 6, 7 and 3 a niodiiled form of con-- struction is shown. lnthis form a frame Li() is provided having side members 40a extendingdownwardly into the bucket and connected by a lower bar 40h. Portions40a and 40h are shown as bent from a single bar and riveted at the upperends of bars loa to the upper part of frame 40.

rame 40 also comprises side plates 40o of general sector shape, the samehaving rearwardly extending projections 39 forming hooks adapted toextend over the rim of the pail 10. A pivot 1":

member Lil extends through and bet' een plates 49o, the same beingheaded at one end and held in place at its other end by the cotter pin42. A member e3, comprising a plate 43a, is provided, the same alsocomprising a pair of angle bars 43h securedto the back of the plate 43a.Pivot 41 extends through the bars 43D so that member 43 is pivoted tothe plates 40e and swingable about the axis of pivot 41. The angle bars43h extend beyond the upper end of plate 43a, which plate is of thegeneral shape of plate 18a already described, said bars being in spacedrelation above said plate. The bar 20 already described having member 2lcarried thereby, is secured between the upper ends of bars 4317 asdescribed in connection with Figs. 1 to 3. A pivot 44 extends throughthe bars 43h below the pivot 4l and a plate 45 is provided of a width tomove between plates 4Go, the same being slightly curved in a compoundcurve and having its lower end bent at an angle and provided with aneyelet through which pivot member 44 passes. Pin 44 is headed at itsends to be retained inthe bar 43h. The plates 40o as shown have curvedtops, the edges of which are bent slightly outwardly, and said plateshave formed therein a plurality of apertures 40d shown as rectangularslots arranged in two rows. Bars 46 are provided extending along theouter sides of plates 40e and having inturned ends 46a adapted to bereceived in one of the slots 40d. Bars 46 are bent transversely and theninwardly substantially ninety degrees, the inwardly extending portions46h having secured therein a headed pin 47 having spaced collars 48thereon. Rollers 49 are journaled on pin 47 between collars 48 and themembers 46D respectively, and said rollers are disposed to engage theouter side of the plate 45. Plates 40o have holes 40e therein at theinner ends of the rows of slots 40d and bolts 50 extend through holes40e and through holes in the bars 46, said bolts having headscountersunk in the plates 40e and being equipped with nuts at the outersides of bars 46. Frame 40 has a drain pan 5l secured thereto beneathplates 43a and 45, the same having a narrow ange about its sides andrear end and having a bottom sloping downwardly into the pail 10.Torsion springs 52 extend about the ends of pin 44 and have one endengaging plate 43d and another end engaging plate 45, said springsacting to move plate 45 away from plate 43a. The plates 40e are providedwith drain holes 40j and plate 45 is provided with drain openings 45a.

In operation, when it is desired to squeeze the mop, the same is placedbetween the plates 45 and 43a and between the side plates 46c. Theseplates define a recess shaped substantially in the form of the sector ofa cylinder. The operator then moves the handle into the hook portion ofplate 21 and swings the handle forwardly transversely of the pail 10.The handle moves plate 2l and member 43 forwardly as indicated in Fig. 7and as said member moves forwardly, plate 45 is moved against therollers 33, said rollers moving upwardly along plate 45 so that saidplate is also moved toward the plate 43. The mop is squeezed between theplates 43a and 45, the water from the mop draining through holes 40j and45a and running down between plates 45 and 43a into the pan 51 fromwhich it drains into pail 10. The bars 56 can be moved to have theirportions 46a extend into different slots 40d and the position of therollers 49 is thus changed. The rollers can be moved either inwardly tocause a closer approach of plates 43a and 45, or the rollers can bemoved upwardly, giving more leverage in the movement of the plate 45.When the mop handle and member 43 are moved upwardly and rearwardly fromover the pail l0, springs 52 move plate 45 to normal position and themop can be lifted from between plates 45 and 43a.

In Fig. 9 the structure is the same as shown and described in connectionwith Figs. 6, 7 and 8, except that in place of having the slots 40d andthe bars 46, holes 40g are provided. Several pairs of said holes areshown disposed at different distances vertically of said plates 40o andalso disposed different distances from the edge of said plate. A pivotbolt 54 is adapted to pass through holes 40e and to carry rollers 55engaging plate 45. Pivot bolt 54 will have a head at one end and be heldat its other end by a Cotter pin. By disposing the pivot bolt 54 in thedifferent holes,the position of the rollers 55 engaging plate 45 can bechanged.

From the above description it is seen that applicant has provided a mopwringer which is simple in construction and which is very easily andconveniently operated. It is not necessary for the operator to bend lowover a bucket of hot or steaming water and the inconvenience of bendingdown over the bucket and also the unpleasant contact with the steam fromthe water, are avoided. The handle of the mop is easily and quicklyengaged with the member 21 and as above described, it is only necessaryto swing the handle of the mop forwardly over the pail to eifect thesqueezing or wringing operation. The mop handle being moved towards andover the pail there is no tendency to upset the pail. The mop iseifectively squeezed or freed of water and the water drains quickly backinto the pail. The device is easily and quickly placed in operativeposition on the pail. The parts are few and the structure is quiterugged. Suflicient exibility is provided to give the desired operatingconditions and to suit the mop being used. The device has been amplydemonstrated in actual practice and found to be very successful andefficient.
